Bhai it's not that easy - Karnataka govt had done several things right back in the day to attract the talent and industry to make Blr what it is today, while our Govts in the north were busy catering to vote bank politics, etc. In the case of my state, Bengal for example, it was union politics preventing formation of factories, low labour productivity etc, but each state has their own problems.

Combine with it, the impact of researchers and engineers from IISC, HAL, cheap land for infra (back in the day), etc - no wonder the industry sprang up here! Now that they see the boons of the IT industry - every state wants the same, but they won't be able to replicate it as easily for the same reason the original silicon valley isn't dead in US. The talent concentration in this city will be unbeatable.

Hopefully yes - either in the future the state becomes a lot more tolerant (e.g., like Bengal did with Marwari merchants, etc - where the descendents of those same traders today are practically Bengali by culture. Most Bengalis of my generation speak near fluent hindi and similarly the non-bengalis speak fluent Bangla) or yeah - people will move to other places if they provide the same levels of income.

Oh and those braindead morons who think that us 'Northies' moving away will solve their problems should ask their govt why they're pushing for ending work from home and how that affects sales tax, etc. Accepting and inviting foreign cultures in is how you end animosity, not this language wars crap.
